ELECTRONIC DEVICE

摘要

Degradation of a battery is prevented or the degree of the degradation is reduced, and charge and discharge performance of the battery is maximized and maintained for a long time. A reaction product, which is formed on an electrode surface and causes various malfunctions and degradation of a battery such as a lithium-ion secondary battery, is dissolved by application of electrical stimulus, specifically, by applying a signal to supply a current reverse to a current with which the reaction product is formed (reverse pulse current).

主权项

1. A method of charging an electronic device comprising:
a first electrode; a second electrode; and an electrolytic solution between the first electrode and the second electrode, the method comprising: supplying a first current that flows between the first electrode and the second electrode in a first direction during a first period; and supplying a second current that flows between the first electrode and the second electrode in a second direction during a second period; wherein the first direction and the second direction are opposite to each other, wherein a reaction product grows on the first electrode by the supplying the first current, and wherein the reaction product on the first electrode is dissolved by supplying the second current.
